Croncrypt
=========

Wrapper to sign and encrypt `cron(8)` output and errors with PGP/MIME before
sending them to the `MAILTO` destination.

    $ crontab -l
    CRONCRYPT_KEYID=0x0A1B2C3D4E5F6G7H
    CRONCRYPT_PASSPHRASE=hibbityboo
    MAILTO=me@mynet
    0 1 * * *  croncrypt rsync /home/tom/important-file /home/backups

The main design goal is simplicity; just whack `croncrypt` in front of all your
`crontab(5)` entries, provided they don’t use pipes or `stderr`/`stdout`
redirects, in which case you should consider putting it all into a script file
anyway.

Don’t use your own GPG key for signing! I recommend you create a dedicated key
just for Croncrypt, and sign it locally with `gpg --lsign` so that your
software trusts it locally.

Installation
------------

Put the `croncrypt` binary somewhere in your `crontab`’s `PATH`, and install
the following Perl modules:

*   `Carp`
*   `IPC::Open3`
*   `Mail::GnuPG`
*   `MIME::Entity`
*   `Symbol`

On Debian-derived systems, this should do the trick:

    # aptitude install perl-base perl-modules \
        libmail-gnupg-perl libmime-tools-perl
